Following on from the previous thread about garden being one big toilet, we have the same problem with neighbours' cats (loads of cats in the neighbourhood). We no longer have cats & everyone else's cars appear to think they can just poo to their hearts content in ours! Previously it was more of an annoyance than an issue, but dd will be learning to toddle by this summer & I want her to be able to use the garden without picking up cat poo (the cats don't bury it).
We have a 20ft garden (live in a terraced house). Any ideas of effective cat deterrents that won't cause harm to the local cats? I am a cat lover but I can't be dealing with the poo issue!
